How would YOU do California/Nevada/Arizona?

[bigfatnick]

Hi all.

This summer i'm in the lucky situation where i'm spending the summer mountain biking in whistler near vancouver, i fly out on the 4th of June. It turns out the weather's a bit crappy in June, so the 3 of us decided we'll go see California, and Nevada etc. The original plan was to drive down from Whistler but it turns out petrol has got expensive in the states too. So now we're gonna fly to LAX, hire a car, and spend a week to 10 days ish driving around.

We have a few places we want to visit but as we're aged 22, 19 and 19, and are all quitting our jobs/students for the purpose of our 3 month jolly money is a big issue. So we really need to work where we should try do it ourself, and which touristy bits we should do the organised tours etc.

So far, we've decided we would like to see...

Hollywood, i was going to just drive around to explore but is it worth going on any tours etc, suggestions would be nice.
Disneyland, should be a laugh
Universal studios, ditto.
San-fransico, all i really know is i should see the bridge, alcatraz, and the steep street. Anything else?
Las vegas, is it even worth going to if everyone bar me will be too young to get in anywhere?
Hoover dam, would you take the tour or just have a nose around?
grand canyon, again, take the tour, in which case which tour? or just drive around it?
And i'm told i should drive the pacific highway, is it as good as people say?

Any other suggestions? I kinda fancy seeing some car stuff, but no-one else particularly car geeky, so it'd have to be good.

Thanks

Nick
